Be it known that 1,DAvin Gf, Run, a citizen of the United States,residing at Providence, in the count ot Providence and State of RhodeIsland, ave invented a new and useful Improvement in Processes otManuacturing Plated Goods, of which the following is a specification.

This invention has reference to an improvementin the process ofprotecting the surface of precious nietal during the act ot forming and.securing the various parts ot an article together in the construction ofthe article.

The object of the invention is to protect the precious metal surfaceagainst oxidation caused by the application of heat in soldering theparts together, also `from scratches or other injury caused by thehandling of the parts in assembling the-rn.

rElie invention consists in the successive steps of the process wherebythe surface of precious metal is protected during the assembling of theparts and in the removal of the protection.

Figure l is a plan View of the blank of one side of a case after thesaine has been shaped lFig. 2 is a section of the blank showing thelayer of precious metal and the supporting layer of base inet-al. Fig. 3is a section of the blank, showing the layer ot precious metal, thesupporting layer ot base metal and the protecting layers.

ln carrying out my invention l irst form or shape the various partsnecessary for the construction of an article of plated metal in therough, that is to say-in a case-.the sides, the lining, the hinges andthe latch. l then electroplate the surfaces of these various parts witha base metal, preferably nickel. I then trim and tit the various blanksor parts and secure the various parts together by solder or otherwise.to assemble the article. After the various parts have been securedtogether and the article is ready for the iinal finishing or polishingSpecification of Letters letent. l Patented flipt?. 29,193.

process, l subject the complete article tov'an electrobath and remove orstrip the outercovering of base metal.l ln the case of the use ottnickel, lr, remove vor strip the nickel surface from the precious metalsurface, leaving the precious metal surface in perfect condition for thepolishing process, free from oxidation or iinjury incidental to thehandling ot the article during the assembly of the same.

Having thus described rny invention,4 claim as new and desire to secureby Letters 1latent l.' The process of protecting the surface of thevarious parts of an article formed of precious plated instal during theconstruction or formation thereoi, the same consist-- ing in plating thesurface of the said parts With a base metal, then. assembling 'the saidparts, and dually removing or stripping the said base metal from thesurface oif said precious metal upon completion of article.

2. The process oflmanufacturing articles of precious plated metal, thesame consisting of electroplating the surface of the various parts ofthe article With nickel to protect saine, then assembling the said partsto forni the complet-ed article, then subjecting the article uponcompletionl to an electrobath to remove the coating of nickel, thusexposing the surface of -precious metal, and nally polishing orfinishing the said surface.

3. The process of protect-ing the surface of articles during theformation thereof, consisting in applyingV a metallic coating to thearticle and then inremoving thel coating upon completion of the article.
